Dear friends, for a good friend of mine we are looking for a spring
like: 1 Feder (=spring): 85 mm breit x 1 mm stark x 5 m lang (=long)
[3.35" wide x 0.039" thick x 196" long]. Where can I find such a piece?
With all my best wishes,

[ It seems like a "clock spring" for a big spring-motor, as in a large
[ musical box. If the core (axle) is 25.4 mm (1") diameter, then the
[ outside diameter of the tightly coiled spring is 84 mm (3.3"). What
[ sort of shop or firm could fabricate a big coiled spring like this?
[ (The same equation is used to compute the diameter of a 10-tune music
[ roll. ;-) -- Robbie
